Why create a Fatigue String Architecture?

Best possible fit up

Counterboring is undesirable or impossible

No loss of material

- 6 -

Stage 1 - Counterbore Planning

- 7 -

Why do Counterbore Planning?

Counterboring is required to manage wall thickness

A single counterbore size is not possible due to WT issues

Improved management of welding process

Why OMS?

Experience managing complex multiple SCR projects

When is counterbore planning carried out?

At any stage between pipe manufacture and pipe yard

Stage 1 - Counterbore Planning

- 8 -

Stage 1 - Bevel Checking

Land thickness, depth and angle

- 9 -

Why check bevel geometry?

Ensures that bevel geometries are within specification

Documentation of specification compliance

Better welds due to consistent land depths, angles and land thicknesses

Why Use OMS Tools?

Fast, accurate, traceable, repeatable, lasting record

When are bevels checked?

Just after bevelling before the firing line

Stage 1 - Bevel Checking

- 10 -

Stage 1 - Pipe Straightness

Laser unit

Target ‘Graticule’ Retro-reflector

- 11 -

Why check straightness?

Quantifying pipe bend and hooking

Ensuring the double joints are straight

Proving contract compliance

Ensuring that spooled pipes are straightened correctly without wasting material by checking on deck

Why use OMS tools?

Fast, accurate, repeatable, traceable, easy to use

When are pipes checked for straightness?

Before and after welding and after spooling

Stage 1 - Pipe Straightness

- 12 -

Stage 1 - Pipe End Squareness

Digital Dial Gauge

- 13 -

Why check end squareness?

Avoidance of out of straight pipe joints

Stress reduction for fatigue senstive pipes

Higher speed welding as time is not wasted rotating pipes to obtain a zero gap

Proof of contract compliance

Why OMS tools?

Fast, accurate, repeatable, traceable, easy to use

When are pipe ends checked for squareness?

Following the bevelling station

Stage 1 - Pipe End Squareness

- 14 -

Stage 2 – Pre-welding activitites

ID Hi-Lo – Closed Gap

ID Hi-Lo – Open Gap

OD Hi-Lo

Dynamic Fit up for Flowlines

Fit up for SCR or Fatigue Sensitive String

Visualisation of pipe end data

- 15 -

Stage 2 - ID Hi-Lo Closed Gap

- 16 -

Why measure ID Closed Gap Hi-Lo?

Longer fatigue life

Less likelihood of a Hi-Lo problem related cut out

Contract requirement

Why use OMS tools?

Faster, accurate, repeatable, traceable

When are ID Hi-Lo’s measured ?

Directly before welding

Stage 2 - ID HiLo Closed Gap

- 17 -

Stage 2 - ID Hi-Lo Open Gap

- 18 -

Why measure ID Hi-Lo?

Longer fatigue life

Less likelihood of a Hi-Lo problem related cut out

Contract requirement

Why use OMS tools?

Faster, accurate, repeatable, traceable, lasting record

When are ID Hi-Lo’s measured ?

Directly before welding

- 20 -

Why measure OD Hi-Lo?

Longer fatigue life

Contract requirement

Why OMS tool?

- 22 -

Why fit up pipes in this way?

The solution achieves the best possible fit up of pipes

Philosophy:Measure + Visualisation Software = Best Fit-Up Achievable, Quicker and Easier

Solution can be tailored to meet client needsBest fit up because actual pipe geometry is used to achieve solution

Minimises logistics necessary to achieve best result

OMS package includes operator training

Why use OMS

Proven system (saving time and money) and easy implementation

When is the the OMS dynamic fit up scheme used?

Near to the firing line or near to the pipe load out

Stage 2 - Dynamic Fit Up Planning for Flowlines

- 23 -

Stage 2 - Fit Up for SCR or Fatigue Sensitive String

- 24 -

Stage 2 - Fit Up Visualisation

Stage 2 - Fit up VisualisationWhy Visualise Pipe End Data?

View measurement data for any pipe end

View simulated fit up of pipes

Best Fit up pipes in spoolbase, on JLay/SLay vessel

Best ID only fit up, or ID and OD fit up

Stage 3 - Internal Weld Scanning

- 27 -

Why perform internal weld scanning?

Elimination of weld defects

Reduction in cut outs at AUT station

Contract requirement

Why OMS Tool?

Fast, extremely high quality images, accurate, recordable data

When to inspect internal welds?

After welding of DJ, in firing-line after hot-pass, in JLay tower, at stalk tie-in
